问题是，当我单击SUBMIT按钮时，在数据库中除了“Nome”之外，我有所有的空白列。我真的不明白这个问题。

附言：我添加了所有变量的回声，事实上屏幕上只打印$nome。谢谢大家!

我很确定您的输入字段需要有一个唯一的id=xxx，否则它将不会以post的形式发送

echo$sql并查看它包含的内容。您确实需要使用准备好的语句，您对脚本上的SQL注入攻击非常开放。这就是我在回显变量和SQL查询时看到的：Registrazione effettuata con successo！Cristiano插入Uteni Nome、Cognome、电子邮件、密码值“Cristiano”、。另一件奇怪的事情是，如果我注册同一封电子邮件，我就不能注册，因为脚本说用户已经存在，我会在PHP脚本的第一部分检查电子邮件，但如果我只签入数据库，则会显示变量$nome，其他变量为blank。我用语句更新代码以防止MySQL注入
